unity C#: find something in a json file from the web

Question

I just want to find a certain property in a pretty long JSON file that I got via this API. Just want to get the movie URL

{
  "data" :{
      "movies": [
           {
           "url" : [ENTER URL HERE]
           }
       ]  
    }
}

just want to get that URL and put it in a variable programmatically for opening in a browser and maybe display in the app

Script that gets the code and makes the json readable to humans:

using System.Collections;
using System.Collections.Generic;
using System.IO;
using Newtonsoft.Json;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.Serialization;
using UnityEngine.XR.WSA.Sharing;
using System.Runtime.Serialization.Formatters.Binary; 
using System.IO;


public class GETFromYTS : MonoBehaviour
{
    [FormerlySerializedAs("URL")] public string url;

    void Start()
    {
        // A correct website page.
        StartCoroutine(GetRequest(url));
       //Application.OpenURL(url);

    }



    IEnumerator GetRequest(string uri)
    {
        using (UnityWebRequest webRequest = UnityWebRequest.Get(uri))
        {
            // Request and wait for the desired page.
            yield return webRequest.SendWebRequest();

            string[] pages = uri.Split('/');
            int page = pages.Length - 1;

            if (webRequest.isNetworkError)
            {
                Debug.Log(pages[page] + ": Error: " + webRequest.error);
            }
            else
            {

                string json = JsonConvert.DeserializeObject(webRequest.downloadHandler.text).ToString();
                Debug.Log(json);


            }    
        }
    }
}

using Jetbrains Rider as IDE

the full json for extra info:

that is the script to get the JSON and display it in the log. just want to sort through the JSON and get that URL — TNT Man Inc, Apr 11 '20 at 13:18
So what? Use a json deserializer and plopp `webRequest.downloadHandler.text` into it, then look for the URL. — Patrick Artner, Apr 11 '20 at 13:20
Does this answer your question? [Deserialize JSON with C#](https://stackoverflow.com/questions/7895105/deserialize-json-with-c-sharp) or [how can I parse json with c#](https://stackoverflow.com/questions/6620165/how-can-i-parse-json-with-c) — Patrick Artner, Apr 11 '20 at 13:20
[https://docs.unity3d.com/Manual/JSONSerialization.html](https://docs.unity3d.com/Manual/JSONSerialization.html) etc. — Patrick Artner, Apr 11 '20 at 13:21
half does, now how do I search it programmatically? have not found a satisfying answer, VERY new to unity and C# — TNT Man Inc, Apr 11 '20 at 13:32
ok, I'm trying to do something with the docs link, hope it works. — TNT Man Inc, Apr 11 '20 at 15:29

Why not using the Unity's built-in JsonUtility static class? Just declare the shape of your data with a class and convert the JSON with it.

[Serializable]
public class Movie 
{
   public string url;
   public string title;
   public string title_english;

   // Include every needed field
}

[Serializable]
public class Data
{
    public Movie[] movies;
}

[Serializable]
public class Response
{
    public Data data;
}

// ... everywhere you need 

Response res = JsonUtility.FromJson<Response>(json);

for (int i = 0; i < res.data.movies.Length; i++)
{
   Debug.Log(res.data.movies[i].url);
}

thanks, but I just found out about simpleJSON, its amazing for what I need to do, and the json2csharp webpage did what you just did. thanks for the response and I'll make this the answer. — TNT Man Inc, Apr 11 '20 at 18:11
